Makes 1 1/2 cups to use as a potato salad dressing

3 egg yolks
2 tsp white wine vinegar
1/2 tsp salt
1/2 tsp dijon mustard
1 cup olive oil
3 tsp boiling water
3 tsp capers
1 gherkin, chopped
500g waxy potatoes
1 small red onion, finely sliced

1 Put the yolks, vinegar, salt and mustard into the bowl of a food processor. Whisk until combined.

2 With the motor running, drizzle in the olive oil until the mayonnaise is thick then add the boiling water.

3 Add the capers and gherkin then stir to combine.

4 Boil the potatoes in plenty of salted water until tender, cool then stir through the mayo. Add the onions, plus extra capers and finely diced gherkin if desired. This is a great recipe to involve any fresh herbs - mint, parsley and dill are all delicious.
